[Qemu-devel] [Bug 547227] Re: qemu-system-m68k does not accept notw %d instruction
As of QEMU 0.12.3, it only emulates ColdFire processors. Coldfire no longer implement notw, only notl instruction, so this behaviour is expected. ** Changed in: qemu Status: New = Invalid -- qemu-system-m68k does not accept notw %d instruction https://bugs.launchpad.net/bugs/547227 You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. Status in QEMU: Invalid Bug description: The notw and notb instructions does not work with latest version of qemu-system-m68k. I've tried both 0.12.3 and the latest git version compiled about an hour ago, both running on Arch Linux. The executable fails with the following output: qemu-system-m68k -nographic -M an5206 -kernel test.elf qemu: fatal: Illegal instruction: 4640 @ 0006 D0 = A0 = F0 = ( 0) D1 = A1 = F1 = ( 0) D2 = A2 = F2 = ( 0) D3 = A3 = F3 = ( 0) D4 = A4 = F4 = ( 0) D5 = A5 = F5 = ( 0) D6 = A6 = F6 = ( 0) D7 = A7 = F7 = ( 0) PC = SR = 2700 - FPRESULT =0 zsh: abort qemu-system-m68k -nographic -M an5206 -kernel test.elf I've attached the test.elf file, which produces the bug. It contains the following: m68k-elf-objdump -m 68000 -D test.elf test.elf: file format elf32-m68k Disassembly of section .text: start: 0: 4e71nop 2: 4e71nop 4: 4e71nop 6: 4640notw %d0 0008 loop: 8: 6000 fffe braw 8 loop It works when removing the not instruction. There might be other non-working instructions, I've only tested a few. Hope you'll get the bug fixed. Thanks.

See `qemu-system-m68k -cpu ?`. QEMU is not targeting it yet, but there's a project: http://www.gitorious.org/qemu-m68k -- qemu-system-m68k does not accept notw %d instruction https://bugs.launchpad.net/bugs/547227 You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU.
